MOTOR-VEHICLE SPEED-ALARM.

Speeiication of Letters Patent.`

T0 all 'whom it may concern.'

Be it known that we, RUDOLPH BERLINER,

` DANIEL D. SWEM, and HENRY F. MOORE,

citizens of the United States, and residing at Chicago, in the county ofCook and State of Illinois, have invented a new and useful Improvementin Motor-Vehicle Speed- Alarms, of which the following is a completespecification.

The main objects of this invention are to' provide a speed alarm formotor vehicles adapted to produce a signal when the vehicle speedapproaches a predetermined maximum; to provide a speedalarm adaptedwhenthe vehicle reaches a predetermined maximum speed to produce acontinuous signal thereafter until released regardless of the subsequentspeed of the vehicle; to provide a speed alarm adapted when the vehiclereaches a predetermined maximum speed to automatically lock thesignaling mechanism in operative position; to provide a speed alarm inwhich the signaling mechanism, when locked in operative position, canonly be released by a properly authorized person; and to provide acheap, simple and durable device adapted to immediately warn the vehicleoperator that he is approaching near to the speed limit.

A specic embodiment of the invention is illustrated in the accompanyingdrawing,in.

which:

Figure 1' is a top plan view of a motor vehicle speed alarm embodied inthis invention. Fig. 2 is a vertical section of the cas- 1 ing with thesignaling mechanism shown in vided on its inner side, near the topthereof,

with a lug 3 and a pivotal pin 4 extends therethrough and into the coverand permits the cover to be swung laterally on the casing, as shown indotted lines in Fig. 1. lOn the outer side of the-casing opposite fromthe pivotal point of the cover is an apertured lug 5, and the cover isprovided with an apertured lug 6 adapted when the cover is in closedposition to register with the lug 5 and permit a lock or seal 7 to besecured through said lugs and lhold the cover in closed position.

Near the bottom of the casing 1 is a trans- .verse bar 8 having on itsupper side a bearing member 9 with a ball-race therein, and

the governor shaft 10 extends upwardly through said bar and bearing tonear the to of the casing. Rigidly secured on the sha t 10, adjacent tothe bearing member 9, is the bearing member 11 having a ball-race in itsPatented May 71, 1912. Application le. September 9, 1911. Serial No.648,427.

under surface which registers with the race in the member 9, and bearingballs 12 are carried in said races. l

Slidably mounted on the upper portion of the shaft 10 is 'a sleeve 13having a flange on each end thereof. The upward movement of said sleeveon the shaft 10 is limited by, a nut 14, and a spring 15 is carried onsaid shaft and bears at one end against the bearing membervll and at theother end against the lower end of said sleeve and normally acts to holdthe sleeve at the upper limit of its movement. The upward movement ofsaid sleeve on the shaft and the tension of the spring against thesleeve are adjusted or, regulated by the position of the nut 14.-. .Armsor links 16 are pivotally connected at their upper ends to the sleeve13, and arms or links 17 are pivotally connected at their lower ends tothe bearing member 11. Governor balls 18' are connected to adjacent endsof said arms and act when the shaft 10 is rotated to move away from theshaft, under the action of centrifugal force and move the sleeve 13downward against the tension of the spring 15.

Rigidl secured on the walls of the casing 1, at polnts opposite orlaterally disposed from the balls 18, are' bells or gongs 19, andpivotally hung on each ball isa hammer 20 adapted t-o strike the bellswhen a predetermined speed of the shaft 1s reached.

Within the shaft 10 is a spring pushed pin 21 which normally bearsagainst the 1nner side of the sleeve 13, and the sleeve 1s provided nearits upper end with an aper- On the lower end of the shaft 10 isA meshwith the gear 23. The shaft 24 is connected with or driven from thedrive mechation of the bells and hammers is so adjusted that as thevehicle speed nears. a predetermined-maximum the 'hammers will strikethe bells and produce an audible signal. Should the speed of the vehiclethen be de- ;creased the hammers will be retracted and the signal cease.If however the speed of the vehicle is increased to the predeterminedmaximum the pin 21 will enter the aperture 22 in the sleeve 13 and holdthe hammers in operative position so that theywill strike ythe bells atany speed of the vehicle, until the4 casing is opened and thepin-released from the sleeve.

While but one specific embodiment of the invention has been herein shownand described it will be understood that many details of theconstruction shown may be varied or omitted without departing from thescope of the claims.

We claim: 1

1. A motor Vehicle speed alarm, comprising a bell, means operativelyconnected with the vehicle adapted to strike the bell at a predeterminedspeed of the vehicle, and mechanism adapted to lock said means inoperative position when the speed of the vehicle is further increased.

2. A motor vehicle speed alarm, compris-` ing mechanism adapted toautomatically produce a signal at a predetermined speed of the vehicle,and means associated with said mechanism adapted when the speed of thevehicle is further increased to lock said mechanism in position tocontinue the signal regardless of the subsequent speed of the vehicle.

3. A motor vehiclespeed alarm, com rising mechanism operated by the ve'cle adapted to produce a signal at a predetermined speed of t-hevehicle, means adapted to lock said mechanism in position to continuethesignal when the speed of the vehicleis further increased, and a casingcontaining the structure thus formed and adapted to prevent said lockingmeans being released except by an authorized person.

4. A motor vehicle speed alarm, comprising, a gong, a centrifugalgovernor, means on the governor adapted to strike the gong at apredetermined speed of the vehicle, and means adapted to lock thestriking means in operative position when the vehicle speed isincreased.

5. A motor vehicle speed alarm, comprising a centrifugal governoradapted to be operatively connected with the Vehicle, a gong positionednear the governor, means on the governor adapted to strike'the gong whenythe vehicle reaches a predetermined speed,

and locking means on the governor adapted to lock it in position for thestriking means to continue to strike the gong as soon as the vehiclespeed is further increased and maintain such position regardless ofsubsequent speed of the vehicle.

6. A motor vehicle speed alarm, comprising a governor shaft, means forrotating said shaft, a slidable sleeve on the shaft, a spring normallyholding the sleeve at its outward limit of movement, governor ballsconnected with the sleeve and adapted to move it against the tension ofthe spring, a gong, means connected with the balls adapted to strike`the gong, and a locking pin on the shaft adapted to lock the sleeve inretracted position and hold the striking means in position to strike thegong.

In witness whereof we have hereunto subscribed our names in the presenceof two witnesses.
